Wilwood Front 14-Inch Drilled Rotor & Red Caliper Conversion, Chevrolet Brookwood/Nomad/Parkwood/Kingswood/Bel Air/Impala/Biscayne/El Camino/Corvette/Sedan Delivery (1959–1964)

Red six-piston calipers and 14-inch drilled/slotted rotors distinguish this Wilwood front hub package. Its Spec-37 rings use 72 curved vanes and separate hats, with BP-10 pads supplied for the selected rotor configuration. The mounting hardware is intended for the individual early Chevrolet applications and matching spindle arrangement described in the fitment entries. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Use DS904 to verify the spindle and wheel envelope before ordering. The hub shifts the wheel outward 0.21 inches per side, so check body clearance separately from the caliper's radial and axial requirements. Confirm the correct hub bolt circle and stud engagement. Hydraulic hoses are separate; the final hose routing, master-cylinder volume and rear brake combination must be suitable for the completed vehicle.

Match the individual model, year, submodel and brake configuration in the fitment table below.
